Book Enhancement of Extended Surface Heat Transfer Using Fractal like Geometries

Download or read book Enhancement of Extended Surface Heat Transfer Using Fractal like Geometries written by Daniel Dannelley and published by . This book was released on 2013 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work investigates a technique to improve extended surface heat transfer through the use of fractal-like geometric patterns. When fractal-like geometries are considered, significant gains in the available surface area for fins can be achieved without large increases in fin volume or mass. For certain fractal patterns, the surface area of a fin can even be increased while reducing the mass of the fin. This would provide direct benefit for situations where the extended surface volume is restricted or minimized weight is desired. Fractal-like geometries are presented to increase the effectiveness and effectiveness per unit mass of fins for natural convection heat transfer as well as increase effectiveness per mass for radiation heat transfer. Common extended surface heat transfer methods and developments were reviewed to obtain an understanding of the focus and limitations of previous work. Based on this literature review, it has been observed that the use of fractal-like geometries has been utilized for engineering applications. However, the use of fractal-like geometries for extended surface heat transfer has not been studied and therefore justified an investigation into their behavior. In an initial investigation, fractal-like fins were manufactured in the patterns of the baseline and first three iterations of the Sierpinski carpet (base width of 0.1016 m, 0.0508 m, 0.0254 m) and modified Koch snowflake (base width of 0.1016 m) in order to quantify practicality and thermal performance. It was observed that fractal-like fins could result in increased fin effectiveness per unit mass by as much as 59%. Motivated by the initial experimental results, subsequent studies utilized computational modeling with a commercially available, industry standard computational modeling program. A computational investigation of iii natural convection heat transfer from fractal-like fins was able to further support conclusions of the experimental results as well as model an additional iteration. Fin effectiveness per unit mass was increased by a minimum of 37% for the conditions tested. Finally, a computational investigation of radiation heat transfer from fractal-like fins showed that fin effectiveness per unit mass increased by a minimum of 25% for the conditions tested.

Available in PDF, EPUB and Kindle. Book excerpt: Two-phase flow heat exchangers are vital components of systems for power generation, chemical processing, and thermal environment control. The art and science of the design of such heat exchangers have advanced considerably in recent years. This is due to better understanding of the fundamentals of two-phase flow and heat transfer in simple geometries, greater appreciation of these processes in complex goemetries, and enhanced predictive capability through use of complex computer codes. The subject is clearly of great fundamental and practical importance.

Book Heat Transfer Enhancement Techniques  With Special Attention to Passive Methods of Heat Transfer Enhancement

Download or read book Heat Transfer Enhancement Techniques With Special Attention to Passive Methods of Heat Transfer Enhancement written by Chakole M.M. and published by Anchor Academic Publishing. This book was released on 2016-06-02 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heat exchangers are widely used in the industrial sector, e.g. in the refrigeration, air conditioning, petrochemical, and agricultural food industry. The high cost of energy and material has resulted in an increased effort aimed at producing high performance heat exchanger equipment. Passive methods of heat transfer enhancement do not need external power for enhancement. One of these kinds of passive technique is twisted tape inserts that enhance the performance of heat exchangers. Using multiple twisted tape inserts gives better enhancement than a single twisted tape insert. Using nanofluid gives also better thermal performance than water. Therefore, nanofluid along with twisted tape inserts was used in this study. For this study, different combinations of multiple twisted tape inserts were designed and fabricated. These different combinations contain dual, triple, and quadruple twisted tapes. Directions of twists are also varied which enables to study the effect of different swirl flow generators. Nanofluid is used with various volume concentrations of 0.07%, 0.14% and 0.21% in order to investigate the effect of nanoparticle concentration on heat transfer enhancement. Experimental investigation was carried out by having a constant heat flux condition and by varying the volume flow rate of flow from 2 to 10 lpm.
